what differentiates it from the other d-series manifolds

 

It's fatter than all the other d series manifolds

 

yup it looks pregnant

 

The one in the picture is actually a D16Y5 manifold because it has EGR. There is no difference between them except for the EGR.

 

fatter main body?

so d16y8 and d16y5 are similar?

whats the d16y5 from?

 

y5 is the 96-00 hx motor

 

so is this a y8 manifold?

It looks like a y8 IM, but it looks like it has a Z6 TB on it.

 

Yes, that is a Y8 manifold. There two flavor of Y8 intake manifold, auto and manual. The Manual will have two holes in the back for the two wire IACV. The auto has none. It uses a 3 wire IACV locate underneath the throttle body.
